Given that,
Length of a solenoid, l = 1.5 m
Diameter of solenoid, d = 4 cm
Radius, r = 2 cm
Number of tunrs per unit length is,
Current, I = 5 A
To find,
The magnetic induction inside the solenoid.
Solution,
We know that, the magnetic induction at the axis inside the solenoid is given by :
So, the magnetic field inside the solenoid is .
